Hi,
The Web Service you are calling is trying to create a long type variable, even you are not passing anything.
Pass 0 for SId, it will work.
Other solution is to modify the schema definition in the WSDL if you can.
If an element is not mandatory then you should specify minOccurs="0" and avoid passing null elements like &lt;SId/&gt; because some XML deserializers try to parse and instantiate an element even you have specified nillable=true in schema definition.
Change &lt;element name="sId" type="long" nillable="true"/&gt; with &lt;element name="sId" type="long" minOccurs="0" nillable="true"/&gt;
and don's pass an element if it is empty.
If you are using Assign activity, it will create empty element if you don't assign value to an element. Use transform activity and if check for empty elements.
